Mithrenniel: I found this tutorial online. Is it what you're looking for?

And hello everyone! I'm getting ready to start a Magical Girl Mami costume, and I'm super excited, but I'm a little confused on the skirt at the moment. I'm not sure whether to make it a regular circle skirt, or a 1 1/2 or two circle skirt. I want it to have the same volume as it does on the show (I plan on putting horse hair braid in the hem to help achieve that), but I don't know if a regular circle skirt will be enough. Any ideas?
